Description
本発明は、電気接続箱に関する。
The present invention relates to an electrical junction box.

上記の電気接続箱においては、バスバーの位置が、放熱板との接触部の位置、およびコイルとの接続部の位置により規定される。ここでバスバーの放熱板との接触部を規定位置とした場合、たとえばバスバーのコイルとの接続部が規定位置よりも高ければ、バスバーが下方に押されて変形し、コイルと接触不良を起こし電気的接続信頼性が低下したり、温度上昇が発生する懸念がある。一方、規定位置よりも低ければ、バスバーが放熱板面から離れてバスバー上の部品の温度が上昇し動作不良となるおそれがあった。
In the above electric junction box, the position of the bus bar is defined by the position of the contact portion with the heat sink and the position of the connection portion with the coil. Here, when the contact portion of the bus bar with the heat sink is set to the specified position, for example, if the connection portion of the bus bar with the coil is higher than the specified position, the bus bar is pushed downward and deforms, causing a contact failure with the coil. There is a concern that the reliability of static connection will decrease and the temperature will rise. On the other hand, if the position is lower than the specified position, the bus bar may be separated from the heat radiating plate surface, and the temperature of components on the bus bar may increase, resulting in malfunction.
